Sexually Transmitted Diseases/Red raised circle what is it

I noticed this 2 weeks ago and it seemed like it happend over night. I notice that it sometimes a layer of dry skin over it. It does not itch nor hurt while examining it. I just want to hear your opinion Doctor. Should I be worried? Thankyou for your time.

AnswerHello Christian,
The rash you have may be caused by several things, ranging from a skin fungus to a benign skin condition, to an infectious STD known as syphilis. You didn't tell me if you are sexually active with anyone, or have any type of chronic skin conditions, or rashes elsewhere. My guess is that a doctor visit is warranted, and if you have been sexually active with anyone within the last 3 months, a blood test for syphilis is warranted.

Expertise

Almost any question or concern about gay men's health issues, sexually transmitted infections, abnormal Pap smears, anal cytology (anal "Pap smears"), etc.
There is no such thing as “d/d free” or “clean” (free of infection), so why do so many of us deceive ourselves into thinking that some people are indeed totally free from a potentially infectious disease, like HIV, herpes, hepatitis, syphilis, chlamydia, warts, gonorrhea, etc., just because they say so? Clinical laboratory tests are not perfect, and having a “negative” or “nonreactive” test does not mean that a person is free from infection. Perhaps at the moment the test was taken, the person was uninfected; or, perhaps, the test wasn’t sensitive enough to detect presence of the infection. There is really no way that anyone can determine that they are truly “disease free,” and there are over a hundred of infectious conditions that can be spread without your knowing anything.
Rather than trying to “pre-screen” or “serosort” a potential sex-mate with deceptive questions that are impossible to know by today’s technologies, a wiser option may be to consider everyone infected with something, and either use appropriate protective measures (“safer sex”), or accept the responsibility and consequences of possibly “catching” something from someone who’s hotter than expected (pun intended!).
There is much research that supports the contention that an HIV positive person reliably taking HIV medications, and having an undetectable viral load, presents a lower risk for transmission of HIV than people who may think or say they are HIV negative, but are not. Food for thought!
